Inscribing brc-20 and Runes in a single transaction

This guide is for reference — actual UI and options may vary slightly, please follow what’s displayed on the inscribe page.

UniSat supports inscribing brc-20 and Runes in a single transaction! This means you can inscribe Runes alongside brc-20 in a more cost-efficient way compared to inscribing them separately.

How is this achieved?

Whether you are inscribing a BRC-20 ticker or making a regular BTC transfer, any Bitcoin transaction with an OP_RETURN data size of 16 bytes or more will automatically mint a runes ticker.

In other words, if the fee rate is 1 sat/vB, the minting cost of 1 runes ticker is 16 sats because of the 16 bytes OP_RETURN data.

What's new?

• Simultaneously inscribe BRC-20 and Runes in one UTXO

• Save on inscribing fees

• Faster & more efficient inscribing

• On both Bitcoin and Fractal mainnet

What are the potential drawbacks?

If you mint 1000 A brc-20 tickers for instance, you will also generate 1,000 B runes tickers, each associated with a separate UTXO. If you do not consolidate these B tickers later, you will only be able to sell them one by one.

Additionally, since BRC-20 tokens and Runes tokens exist within the same UTXO, some applications may have difficulty distinguishing between them, potentially leading to asset misidentification and loss.
